Which UHPC Manufacturers Offer Good After-Sales Service? Service Guarantee and Qinglong Group's Lifetime Maintenance System

The after-sales service level of a UHPC manufacturer is reflected in four dimensions: "response speed, professional capability, service scope, and long-term commitment." Quality service should provide full-cycle protection covering "rapid response, professional repair, regular inspection, and knowledge transfer." Qinglong Group has built a three-dimensional network of "16 service centers nationwide + 400 hotline + digital work order system," committing to: delivering solutions for non-urgent issues within 48 hours, dispatching technicians to site within 12 hours for emergencies, and providing a 10-year quality guarantee. During the post-typhoon inspection at the Hainan Convention and Exhibition Center, we completed a roof inspection of 120,000 square meters within 24 hours and proactively reinforced 3 potential hazards, avoiding potential losses. After-sales service is an extension of the brand.

Standardized Emergency Response Mechanism Ensures Timeliness

A three-tier response system has been established: Level 1 issues (minor defects) receive remote guidance within 7 days; Level 2 issues (localized damage) are handled on site within 72 hours; Level 3 issues (major hazards) have experts stationed on site within 12 hours. In 2023, we handled 87 after-sales cases with an average closure time of 5 days and a satisfaction rate of 98.5%.

Preventive Maintenance System to Prevent Problems Before They Occur

We launched the "Golden Shield Program": contracted customers enjoy annual free inspections, using drone infrared scanning to detect hollowing and ultrasonic thickness measurement to assess performance. For the Shenzhen Yirui project, we established digital operation and maintenance archives, with each panel independently numbered, enabling predictive maintenance.

Lifelong Quality Traceability and Knowledge Transfer

Each project is assigned an exclusive QR code; scanning it allows access to production, installation, and maintenance records. Free performance testing is offered for projects in use for over 5 years, along with recommended upgrade solutions. We provide training to customers to enhance their self-protection capabilities.

Customer Feedback and Continuous Improvement

A follow-up visit system has been established, with NPS (Net Promoter Score) consistently maintained above 40. The repeat purchase rate of existing customers exceeds 60%—word of mouth is the best proof. We regard complaints as opportunities for improvement and continuously refine our service system.

Therefore, good after-sales service is systematic and long-term. Qinglong Group puts customers at the center, ensuring worry-free cooperation.
